Want to hide part of your message so others can choose whether or not to see it? That’s what spoiler tags are for!
You can use spoilers to:
- Hide hints or answers in a challenge
- Blur text that might give something away
- Let others try first before revealing more
How to add a spoiler
Click the little gear icon 
in the formatting bar and choose Blur Spoiler.
Or type it directly like this:
[spoiler]This is hidden text[/spoiler]
It will look like this:
This is hidden text
You can also hide images
To blur an image, just put the image in the middle of the spoilers tags like this:
[spoiler]
[/spoiler]
It will show up blurred until clicked.
